Three dimensional finite element analyses of the single-side repaired panels using glass/epoxy composite are performed considering the general mixed mode conditions and real crack-front shape modeling (RCFM) during the crack propagation procedure. Variations of the fracture parameters through the thickness of the panels for the initial crack configuration and crack growth behavior of the repaired panels with various patch lay-ups are investigated. The effect of considering K
_III on the small and large crack growth of repaired panels are also studied. The obtained lives are compared with the previously obtained lives using simplified FEM procedure and experimental results by the authors.
